BED-BOTTOM.

Specification of Letters Patent. Patented Apr. 27, 1915.

Application led December 1, 1913. Serial N o. 804,023.

To all whom it may concern.

Be it known thatl, EMIL LEHMANN, a citizen of the United States, residing at Hammond, in the county of Lake and State of Indiana, have invented certain new and useful Improvements in Bed-Bottoms; and

I do declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use' the same. v

This invention relates to beds, and more especially to bed bottoms of fabrics and springs; and the object of the same is to l5 produce a bed bottom of this character wherein the fabric portions are readily detachable from the metal portions so that both may be cleaned.

To this end the invention consists in the details of construction hereinafter t more fully described and claimed, and as shown in the drawings wherein- Figure 1 is a side elevation and Fig. 2 a bottom plan view of this device complete.

Fig. 3 is a section on the line 3 3 of Fig. 1, Fig. 4 a sectional detail on the line 4 4 of Fig. 2, and Figs. 5, 6, and 7 are sections on the lines 5 5, 6 6, and 7 7 of Fig. l. Fig. 8 is a perspective detail of one corner of the cover. Fig. 9 is an enlarged detail of one of the hooks having a slotted shank.

Within a rectangular frame 1 of L-iron -are secured slats 2 composed of notched metal strips standing on edge, and in the upper notches of these slats are secured the smaller ends of inverted conical springs 3 whose larger upper ends rise to about the same height and are inclosed within a wire frame 4 to which the outer sides of the upper convolutions of said springs are attached as at 5. The smaller coiled ends of the spring are securely fastened to the slats 2 by fastening wires 44. There is a single wire for each row of springs which are disposed at right angles to the slats 2'within the frame 1. This fastening wire is first bent over one of the smaller coiled ends of a springB that is secured in the notches at the top of the slat 2 at a point on one side of the slat, then down under the said slat,

through the notch in the bottom thereof, 'up

the other side, and then out over the coil .at a point diametrically opposite from outermost springs said upper convolutions are connected with each other by means of wire links 6 hooked at their outer ends as at 7 to the convolutions and hooked at their inner ends as at 8 to small metal rings 9 as shown. That much of my invention which has been described is made completely of metal, and it may be painted, japanned, gal vanized, or otherwise treated to prevent rust, especially when the fabric portions are removed and this much of my invention is cleaned as by turning the hose on it.

Overlying the structure described above is a pad 10 which may be made thick enough to be called a mattressor may be composed of two fabric sheets with padding or stufling of any character between them, and to the under side of this pad near its edge`s are attached hooks 11 in such positions that they may be engaged over the wire frame 4 to hold the pad in place and allow the margin l2 of the pad toproject a little beypnctl said frame and hang down outside o 1 Overlying the pad is the cover 2O which is by preference composed of a single ply of stout fabric suitably ornamented to forni the top of the bed bottom if the same is to be used in a boxzcouch which is my invention. At its edges this cover is bent downward for a short distance to form a margin 22, the ends of the surrounding margins being stitched together for about an inch downward at the corners of the cover as indicated at 21, below which they are left free and provided with eyelets 23 so that they may be laced together as seen at 24. Thus the margins are continued downward into what might be called flaps 25 whose Width is sufficient to permit them to cover all sides of the coiled springs, and the lower edges of these flaps are turned upward into casings 26, each of which contains a stiff Wire 27. lThe four wires therefore constitute a frame, although they are disconnected entirely from each other, as also are the flaps 25 excepting when the lacings 24 are drawn up tight as shown. For securing said flaps4 ioo ' cover,

to the outer leaf of the L-shaped frame 1, the latter is provided with a series of upright rivets or headed studs 28, and on each of the same beneath the frame-leaf is slidably mounted the slotted shank 29 of a hook 29 whose bill 29" is adapted to engage over the reinforced or beaded lower edge of the iiap. Thereafter the slotted shank of the hook is pushed inward along the headed stud or rivet 28,`so that the bill 29" passes through the fabric of the iap just above the wire 27. When now it is desired to remove the these hooks 29 are slid outward over the headed studs 28 s o that their bills 29 disengage saidwires 27 and the entire cover with its margins and flaps can be raised olf of the metallic portion of the structure and the pad; after which said pad calil be unhooked and removed as will be clear.

Underlying the slats is a bottom consisting of a sheet 30 of fabric having independent casings 36 aroundits four sides, each inclosing a wire 37, and around each of said wires at intervals is loosely mounted an eye 39 at the inner end of a hook 39 whose bill 39 is adapted to be engaged with an eye 38 which latter may be simply a hole vformed through the lower leaf of the L-shaped frame 1 and at a proper point. The beaded edges of the bottom piece 30 give it stiffness, and yet as the wires 37 `forming the beads are independent of each other, each may be drawn toward the corresponding side bar of the frame 1 when its hooks 39 are to be engaged with the holes 38 therein. The tips of the bills 39 of said hooks pass completely through the lower leaf of the frame 1 and in no way interfere with the use of the latter as when it is placed within the boX if this device be used as the mattress of a boX couch. i

To the under side ofthe lip of each side bar of the frame at two points are riveted at 40 loop-shaped fabric handles 41, each of which has on its inner side a hook 42 adapted to engage an eye 43 stitched to the outer side of the margin 22 of the cover 20, this hook-and-eye connection causing the loop-shaped handle to stand upright. The rigid attachment of the lower end of the handle to the metal frame applies the lifting force direct to the heaviest portion vof the device when the latter is to be raised out of its box-shaped frame (not shown) or placed therein. I have stated that said handles are of fabric, but if the device is to be washed by turning the hose on it, it may be well to make said handles of leather or some other iexible material which is not injured by water.

To assemble the parts, the metal structure is inverted and the bottomplaced thereover, its hooks 39 being engaged with the eyes or holes 38 in the frame 1; then the structure as thus built u is reversed, and

and after the parts are separated those which are offabric may be cleaned as by washing or dry-celaning, and those which are of metal may be cleaned by turning the hose onto them.

In the use of this device, when a load is placed on the top the springs are compressed and the air within the structure is forced out from beneath the flaps and between them and the frame 1, and also between the frame 1 and the edges of the bottom; butthe iiaps themselves may not bulge laterally outward because they are laced together at their ends as at 24. Thus the entire device may fit into the upper end of a box and form the mattress of a box-couch, and to this end the shape of the frame 1 is particularly adapted. Moreover the form and disposition of the various hooks oder no obstruction to such use of the frame, nor to other uses of it if desired. The proportions and precise materials of parts are obviously not essential to the successful operation of the invention.

What is claimed as new is:

1. In a structure of the character described,

a vertical rectangular shaped metal frame 4and supporting a pad and cover, iiaps hanging from the sides and ends of said cover, having at their lower edges hems adapted to incase independent wire rods, wire hooks having slotted elongated Shanks slidably mounted on said studs, the bills of said hooks being adapted to pass transversely through said hems and engage over the rods inv said hems, whereby the said flaps are held taut between the frame and cover substantially as described. v

2. In a structure of the character described, a vertical rectangular shaped metal frame having a horizontal lip projecting outwardly near its top, said frame comprising ends and sides, loop-shaped handles riveted to the bottom of said lip along the two sides of the metal frame, said loop handles having hooks on their upper sides near the top of the loops, a plurality of coiled )springs mounted on`\spaced slats across the having eyes, whereby `the said hooks on the bottom of the frame, a padand a cover, said In testimony whereof have hereunto set springs supporting said pad, said cover havmy hand in presence of two subscribing wit- 10 ing end and side flaps secured to the frame messes.

at the bottom of said lip, and said side flaps EMIL handles can be engaged with the eyes on the Witnesses: flaps to cause the loop handles to stand up- WILLIAM H. GosTLER, Jr.,
